抗抑郁剂疗效的预测因素分析

目的:探索影响抑郁症患者抗抑郁剂疗效的预测因素。方法:241例抑郁症患者给予抗抑郁药治疗6周,治疗前后进行汉密顿抑郁量表17项(HAMD)评分,采用减分率评定疗效。分析人口学因素、基线HAMD、明尼苏达多项人格测定(MMPI-2)、认知功能评分及脑源性神经营养因子(BDNF)、5-羟色胺转运体(5-HTTLPR)和糖皮质激素受体(GR)3种基因多态对疗效的预测。结果:基线HAMD评分(β=0.771,P0.001)、MMPI-2中偏执(Pa)分(β=-0.322,P=0.032,R2=0.451)、连线测验B评分(TMT-B)(β=-0.045,P=0.013)、汉诺塔总分(β=-0.067,P=0.026)、数字广度(倒序)分(β=-0.974,P=0.025)及GR BclI基因G-等位基因携带者(P=0.05)与抗抑郁剂HAMD减分率有关。整合模型回归分析显示,结合基线HAMD评分(β=0.894,P0.001)、MMPI-2-Pa分(β=-0.155,P=0.036)和TMT-B分(β=-0.038,P=0.034)3个预测因子可解释57.1%的变异。结论:基线HAMD评分、MMPI-2-Pa分和TMT-B分可预测抗抑郁剂的疗效。

Objective To evaluate the association of 2616c/T polymorphism in iron regulatory protein 2(IRP2)gene with Alzheimer disease(AD)and Vascular dementia(VD).Methods In this study,281 patients with AD,60 with VD,and 285 normal aged were recruited.The 2616C/T polymorphism in IRP2 gene was analyzed by using polymerase chain reaction-restriction fragment length polymorphism.And the cognitive function was assessed with the Mini-Mental State Examination(MMSE).Results (1)No significant difieFences were demonstrated in IRP2 genotype or allele frequencies between AD patients and controls(χ2=2.46,P=0.292;χ2=2.17,P=0.141 respectively).However,when AD patients were stratified by disease severity.the frequency of T allele carriers in the moderate to severe AD patients was 78.0%,significantly higher than that in controls(69.8%;χ2=4.106,P＜0.05).Logistic regression analysis demonstrated that the age-,sex-and ApoE-adiusted OR of modcrate to severe AD patient with T allele was 1.62(95% CI=1.03-2.54).The frequency of T allele carriers or T allele in VD patients was higher than that of controls,but the difference was not statistically significant(P＞0.05).(2)The frequency of tit genotype or T allele in the moderate to severe AD patients was significantly higher than that in mild AD patients(25.8%vs.12.5%,χ2=5.477,P＜0.05;51.9%vs.40.3%,χ2=5.803,P＜0.05 respectively).(3)MMSE scores of the AD patients with TT genotype was significantly lower than ones with CC or CT genotype(P=0.028;P=0.014 respectively).Conclusion The 2616C/T polymorphism in the IRP2 gene is possibly associated with moderate to severe AD.but not associated with VD.And the TT genotype may be a risk factor for cognitive impairment of patients with AD in Chinese Han.

双相障碍误诊及患者求医轨迹

目的了解双相障碍患者被误诊情况、临床特点和求医轨迹,为双相障碍的识别和诊疗提供参考。方法根据目前诊断和首次诊断是否相同,将2007年6月-2010年10月在广州市医科大学附属脑科医院就诊的处于抑郁发作期的247例双相障碍患者分为误诊组和确诊组,通过调查、访谈及问卷法收集患者资料,比较两组临床特点和求医轨迹。结果检出确诊病例72例,误诊患者175例,误诊率为70.85%。误诊病例中被误诊为单相抑郁障碍的最多(64.00%),其次为精神分裂症(22.29%)。与确诊组相比,误诊组有更高比例的病前生活事件(41.9%vs.23.6%,P0.01)、过去存在更高比例的轻躁狂症状(70.9%vs.55.6%,P0.01)、间歇性病程更少(55.2%vs.70.8%,P=0.02),而确诊组更多患者首次即去精神病专科医院就诊(83.3%vs.70.3%,P=0.03)。结论具有病前生活事件、轻躁狂症状以及间歇性病程更少的双相障碍患者应尽早到精神病专科医院就诊,以提高确诊率。
